Our most important sources for the Return are the books known as Ezra and Nehemiah in Catholic and Protestant bibles. The Jews have a single book, called Ezra. There a whole bunch of other books of Ezra, many to be found in Russian and Greek bibles. 1 Esdras, 2 Esdras, 2 Esdras, Latin Esdras, Esdras Alpha, the Greek Apocalypse of Ezra, the Latin Vision of Ezra, the Questions of Ezra, the Revelation of Ezra. What a muddle! Colombus used 4 Esdras to discover America.
